This system does not have AFM valves but is equipped with NPP valves. For 2017 to 2018 Grand Sport it fits manual transmission only. Borla cat-back and axle-back systems use patented straight-through, multi-core technology to free hidden horsepower while adding exhaust velocity, driving excitement, and the distinctive Borla Sound of Power. Each system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC precision for an accurate fit. Borla exhaust is handmade in the USA. As a street axle-back system it is 50-state emissions legal. Non-moving parts are covered by the Borla Million-Mile Warranty and the exhaust valves carry a one-year warranty; failures of original equipment AFM and NPP actuators are not covered.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem type: axle-back exhaust\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 austenitic stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: all-welded, mandrel-bent, patented straight-through multi-core\u003c\/li\u003e\n\u003cli\u003eExit style: center rear exit\u003c\/li\u003e\n\u003cli\u003eTips: quad 4.25 inch round rolled, angle cut, polished\u003c\/li\u003e\n\u003cli\u003eHas NPP valves; does not have AFM valves\u003c\/li\u003e\n\u003cli\u003eFor 2017 to 2018 Grand Sport, fits manual transmission only\u003c\/li\u003e\n\u003cli\u003e50-state emissions legal\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 11905\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2015 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2016 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2017 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2018 Chevrolet Corvette\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhich C7 Corvettes does this fit?\u003c\/h5\u003e\u003cp\u003eIt fits 2015 through 2018 Chevrolet Corvette C7 Z06, and 2017 through 2018 Grand Sport with manual transmission only.
